Wireless Telegraphy

England. Guglielmo Marconi began his wireless experiments in 1895, and on 2 June 1896 filed his provisional specification of a patent for wireless telegraphy. He demonstrated the system to the British Post Office in July. The British patent was accepted on 2 July 1897, and the US equivalent on 13 July 1897. In March 1896, Alexandr Popov demonstrated a similar wireless system in Russia, having demonstrated a more rudimentary system a year earlier.
